Sengkang West Single Member Constituency was a single member constituency (SMC) in the north-eastern region of Singapore. At abolition, it was managed by Ang Mo Kio Town Council.
Prior to the 2011 general election, the constituency was formed from the Sengkang West division of Ang Mo Kio Group Representation Constituency (GRC). Lam Pin Min, Member of Parliament (MP) representing the division, stood for election in the SMC; he defeated Koh Choong Yong from the Workers' Party (WP) with 58.1% of the vote.
In 2015, part of the SMC was returned to Ang Mo Kio GRC; Lam won 62.1% of the vote in a rematch against Koh.
For the 2020 general election, the SMC was abolished and split into two parts; one was returned to Ang Mo Kio GRC, the other merged into the newly created Sengkang GRC.
